[POWERPC] Fix return from pte_alloc_one() in out-of-memory case
pte_alloc_one() is expected to return NULL if out of memory. But it returns virt_to_page(NULL), which is not NULL. This fixes it. Cc: Paul Mackerras <paulus@samba.org> Signed-off-by: Akinobu Mita <mita@fixstars.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
